BACKGROUND: Tuberculosis itself causes not only lung parenchymal destruction but also pulmonary vascular damage. Secondary emphysema also causes pulmonary vascular damage, which can develop as a late sequela of pulmonary tuberculosis. Therefore, pulmonary circulatory impairment tends to be more severe in post-tuberculosis emphysema than in primary emphysema. In post-tuberculosis emphysema, the right ventricular function may play an important role. However, little information regarding the right ventricular function is available. The purpose of this study was to evaluate and compare the right ventricular function between post-tuberculosis emphysema and primary emphysema. METHOD: Post-tuberculosis emphysema(PTE) or primary emphysema(PE) was diagnosed by history, HRCT finding and pulmonary function. Twenty patients with post-tuberculosis emphysema were matched with 20 patients with primary emphysema according to both FEV1 and FVC. Arterial blood gas analysis and echocardiography were done at rest and immediately after symptom-limited exercise. The right ventricular function was evaluated with the right ventricular ejection fraction using a modification of Simpson's method. RESULTS: There was no significant difference inthe demographics and pulmonary function between the two groups. In post-tuberculosis emphysema, the PaCO2 was higher (42.9±4.7 vs 38.8±3.1 mmHg at rest ; 47.9±7.0 vs 41.1±5.9 mmHg after exercise ; p<0.01) and the right ventricular ejection fraction was lower (57.6±6.5 vs 61.4±4.7 % at rest ; 51.1±10.8 vs 59.8±6.6 % after exercise ; p<0.01) both at rest and after exercise. The PaO2 after exercise was also lower (65.7±12.6 vs 80.2%±14.4 mmHg, p<0.01), while the PaO2 at rest tended to be lower(82.9±12.0 vs 87.8±7.5, p>0.05). In both groups, right ventricular ejection fraction correlated with the PaO2 after exercise(PTE r=0.536, PE r=0.557), and the PaCO2 at rest(PTE r=-0.576, PE r=-0.588) and after exercise(PTE r=-0.764, PE r=-0.619). CONCLUSION: Impairment of the right heart function and gas exchange were more serious in post-tuberculosis emphysema than in primary emphysema, and gas exchange may be influenced by the right ventricular function in post-tuberculosis emphysema.

Left ventficular ejection times were measured by four different methods in 200 healthy males and females from the polygraphic tracings including an apexcardiogram, a phonocardiogram and a carotid pulse tracing. The results obtained by each method were compared and the adequacy of each method was critically reviewed. It was felt that the method measuring the left ventricular ejection time from the carotid pulse tracing was the most reasonable. However, there was a significant correlation between the carotid-derived values and those obtained by other methods, thus, regression equations for the relationship of the latter values to the fromer were obtainable.

Pure red cell aplasia in uncommon disorder characterized by finding of anemia, absence of nucleated red blood cell in the marrow, absence of reticulocytes in the peripheral blood and normal peripheral platelet and leukocytes counts. We experienced one case of pure red cell aplasia associated with hemolytic anemia characterized by hemoglobinuria, reticulocytopenia, and erythroid hypoplasia of the bone marrow. The cause of the illness was not definitely identified, but we concluded that this patient had simultaneous occurrence of PRCA and hemolytic anemia following administration of diphenylhydantoin after craniotomy rather than virus or bacteria induced. The simultaneous occurrence of PRCA and hemolytic anemia in uncommon and the mechanism for diphenylhydantoin induced PRCA and hemolytic anemia is unclear.

Clinical study on 62 patients (26 males and 36 females) with neurofibromatosis seen during past ten years at the Department of Dermatology, Pusan National Universitg Hospital, was made the variable clinical manifestations of the disease and Riccardis ciassification were emphasized. The results were as follows . 1) Family history was noted in 32 cases(51.6%) and exhibited autosomal dominant inheritance pattern. 2) Cutaneous neurofibromas were found in 52 cases(83.8%). 3) Cafe-au-lait spots, measuring greater than 1.5cm in its longest diameter, were found in 60 cases(96.8%) and 44 cases(71.0%) had more than 6 in number. 4) Among associated abnormalities were,' mental retardation(20,9%), skeletal abnormalities(11.2%), seizure, severe headache, etc. 5) According to Riccardis classification, 38 cases could be classified as type I, 28 cases(73.7%); type II, 0 case ; type III, 1 case(2.6%); type IV, 3 cases(7, 9%); type V, 1 case(2.6%); type VI, 4 cases(10.5%); type VII, l case(2.6%); and type VIII, 0 case.

The search for tumor-avid agents for use in nuclear medicine imaging is an ongoing field of importance. The purpose of this study was to determine the affinity for radiolabeled vitamin B12 by a wide histologic variety of tumor types in mice. Seventeen different types of tumor were grown subcutaneously in female Balb/C or Balb nu/nu(nude) mice. When the tumors reached about 1 cm in diameter, mice were injected intraperitoneally with 57Co-vitamin B12. Twenty-foul hours later, the mice were sacrificed. Organs and tissues were removed, weighed, and activity per mg determined by gamma counter. Values represented cpm/mg tissue that was normalized to 20 grams body weight for each mouse. A wide variety of tumor types showed significant uptake and concentration of 57Co-vitamin B12, as evidenced by tumor:tissue activity ratios. For many tissues of great importance in terms of background(bone, muscle, blood), the tumor:tissue activity ratios of uptake were high. These data strongly suggest that further efforts to evaluate the utility of radiolabeled adducts of vitamin B12 for clinical use in oncologic imaging are warranted.

PURPOSE: This study was to explore the effects of breast cancer education for college students on their mother's breast cancer screening promotion. METHODS: This study used a one-group pretest and posttest design. Data were collected from September to November, 2007 from a sample of 80 college students and their mothers using a survey questionnaire, which asked about demographic variables, concerns over health and breast cancer, communication, stage of change and attitude (pros and cons) related to breast cancer, and confidence in breast self-examination. The college students received education about breast cancer for 50 minutes and then they educated their mothers about breast cancer. Data were analyzed with descriptive statistics and paired t-test. RESULTS: The mean age of the college students was 22.0 years, and that of their mothers 49.4 years with a range from 43 to 58 years. After receiving education on breast cancer, there were significant changes in the mean scores of concerns about health and breast cancer, communication, pros in mammography, and confidence in practicing breast self-examination. CONCLUSION: This study indicates that education on breast cancer to mothers through their college-age daughters is effective and can be utilized to promote breast cancer screening for women.
